The effects of indigestible dextrin obtained by heat-moisture treatment of HCl-adsorbed corn starch on cholesterol metabolism were investigated. Four-week-old male Wistar rats were fed diets containing indigestible dextrin of a 5% level with or without cholesterol for 21 days. A fiber-free diet was used as a control. Serum total cholesterol level was significantly decreased in the rats fed the indigestible dextrin diet without cholesterol compared to the rats fed a fiber-free diet, but there was no difference in fecal excretion of bile acids between the dietary groups. Ingestion of indigestible dextrin significantly increased cecal weight and lowered pH of cecal contents. These results suggest that the hypocholesterolemic effect of indigestible dextrin is not explained by the increase of fecal excretion of bile acids.
